Technology Core Network & Wireless Infrastructure
Network Switch Retrofit
Wi-Fi Expansion for Elementary Schools
Telephony System Upgrade
Background & Justification
Network Switch Retrofit – The district access switches need to be retrofitted to maintain operability. We will replace the oldest switches 1st, then use those as spares for the rest of the district. At end of life, the vendors stop making security updates that leave the devices open to new exploits as they are discovered. The requirements continue to grow as well. These switches will now power the phones, wireless access points, security cameras and door access control. Due to the critical nature of some of services, the switches need to have the technology to be resilient and continue operating with a power supply failure as well as redundant upstream connectivity. A Core router will be installed at a secondary data center site to allow for more resiliency in the core network and speed to recover services at another location if needed.
Wi-Fi Expansion for Elementary Schools ‐ The main objective of this initiative is to design a robust Wi-Fi environment that is built around the classroom rather than the building layout. This means that more access points need to be added to cover the student digital learning experience in each classroom. The added access points will allow Katy ISD to build on the current infrastructure to ensure a robust Wi-Fi connection from the classroom for both District and student ‐owned devices. This reliable and high speed access will provide for the increasing demand of connectivity for students to access digital resources such as online assessment, multi‐media content, animations, multiple languages, webinars, and collaboration.
Telephony System Upgrade – To stay current with software updates both security and feature, KISD will be upgrading the telephony system to the current version. This is to ensure that our voice communication system for the district is reliable. This will include retrofit of the Voice Gateway routers and IP Phones that are end of life.
Enterprise Systems‐Payroll clocks upgrades ‐ Due to the age, condition and specifications of the District time clocks, it is necessary for us to replace the devices that are not performing to current standards. Replacing time clocks will allow us to remotely administer and service this equipment.
Projected Cost Breakdown
Replacing network access switches. Price of a switch ranges from $5,000 for a normal Cisco switch to $85,000 for a core Cisco switch.
Wi‐Fi (Wireless Access Points) expansion for all elementary schools. High school expansion will be completed July 2015. This is the second phase of the expansion. This includes cabling and additional switches.
